我正在開發一個

Android應用程序,并希望集成Twitter.

我所理解的是,如果在用戶的設備上安裝了官方的Android Twitter應用程序,那么我們可以使用賬戶經理進行身份驗證,如果沒有安裝,則顯示twitter登錄網頁.

我的理解是否正確？

現在使用twitter web登錄頁面進行身份驗證工作正常.但是如何使用客戶經理登錄？

使用AccountsType作為“com.twitter.android.auth.login”

我使用來自的客戶經理獲得了令牌和令牌秘密

?com.twitter.android.oauth.token

?com.twitter.android.oauth.token.secret

我正在使用Twitter4J,并使用我的CONSUMER_KEY& CONSUMER_SECRET和recvd.令牌.但身份驗證始終失敗.

CONSUMER_KEY& CONSUMER_SECRET是我在twitter上注冊應用程序時獲得的密鑰…但我不明白如何在官方Android Twitter應用程序身份驗證中使用這些密鑰？

PLS.讓我知道謝謝

這是我的代碼
